IMPORTANT SAFETY INFORMATION

1. All fifth wheel maintenance must be performed by a qualified service technician using proper tools and safe procedures.

2. Use only genuine SAF-HOLLAND parts.3. Wear safety goggles during disassembly and

assembly of the fifth wheel.4. Keep fingers away from all potential pinch

points in the fifth wheel.5. Do not weld on this product. Do not deviate

from the instructions contained in this manual. Any changes or deviations from these procedures will void all warranties, express or implied, unless prior written consent is obtained from Holland.

6. Always verify proper operation and adjust the fifth wheel following the procedures contained in this manual before placing back in use.

Disassembly and Inspection:1. Remove the fifth wheel from the tractor.

2. Place fifth wheel upside down on a well supported work surface.

3. Completely disassemble the fifth wheel.

DIsCARD ALL REmOVED COmPONENTs! DO NOT RE-UsE ANY PARTs!

4. Thoroughly steam clean the top plate.

5. Inspect the top plate for cracks and flatness. If the top plate is cracked it must be discarded. The lock pin (Item 12) and adjusting pin (Item 3) on the SAF-HOLLAND FW17 Series are slip fit. They are not designed to be press fit like other SAF-HOLLAND fifth wheels. However, if either hole is elongated, the top plate must be replaced.

NOTE: The maximum allowable lock pin hole diameter is 1.429.̋

The maximum allowable adjusting pin hole diameters are 1.672˝ (top) and 1.172˝ (bottom).

Do not attempt repair or service if the top plate is cracked or

distorted. The top plate must be replaced. Failure to replace the top plate could result in tractor and trailer separation which may result in death or serious injury to others.

All of the required parts in this kit MUST be used. DO NOT substitute

other or used parts. Improper part combinations can cause the product to couple improperly and may result in death or serious injury to others.

Fifth Wheel Assembly1. Insert the release handle (Item 5) “S” bend

through the rib handle window, as shown in FIGURE 1.

2. Lubricate both holes of the release cam (Item 4) with Never-Seez. Also lubricate both sides around the cam slot and the cam slot itself with grease, as shown in FIGURE 2.

3. Refer to FIGURE 3 for the following two steps: a. Install the release cam (Item 4), onto the

“S” bend so that the end of the “S” bend is facing up.

b. Articulate the release handle (Item 5) and release cam (Item 4) so that the release cam can be fed through the slot in the main rib.

fifth wheel does not operate properly, contact your local Holland Representative for assistance. Failure to properly operate this fifth wheel could result in tractor separation, which may cause death or serious injury to others.

Inspection – Locking Mechanism1. Verify the proper operation of the fifth wheel

by locking and unlocking the fifth wheel using a SAF-HOLLAND Kingpin Lock Tester TF-TLN-5001.

2. Set tool on the fifth wheel, engage the “J” hook, and rotate the handle to lock.

3. Pull the handle rearward to unlock.

4. After each attempt, verify that the fifth wheel is properly locked, as shown.

5. After unlocking, verify that the handle ‘kicks off’ the unlock notch and moves into the ready to couple position.

Adjustment – Locking Mechanism 1. Using ONLY a SAF-HOLLAND TF-TLN-5001 Lock

Adjustment Tool, lock the fifth wheel and verify that it is closed as shown in previous step.

2. Slide the adjustment tool forward and backward to check for play between locks and king pin. Ensure that the tool remains flat with full contact on the fifth wheel top plate. If free play exceeds 0.080˝, adjust locks.

3. To adjust locks, unscrew the socket head cap screw until the head clears the adjusting pin and rotate the adjusting pin counter-clockwise until the next notch lines up with the sockethead cap screw. Re-tighten the sockethead cap screw. Adjust only one notch at a time.

4. Verify the proper adjustment by locking and unlocking the fifth wheel several times with the lock tester. Check that the fifth wheel is properly locked as shown on the left (Inspection – Locking Mechanism).

5. Rotate the lock adjustment tool from side-to-side to ensure that the locks are not overtightened. The locks should not grip the king pin and the tool should rotate freely.

6. Re-check for free play in locks by sliding the adjustment tool. Freeplay should be .040˝ minimum. If there is still excessive free play in the locks, repeat procedure and adjust one more notch. If the adjustment is still unsatisfactory, the casting may not be rebuildable.
